[Lustre-discuss] device 'stuck' in lctl

[Andrus, Brian Contractor]

All,



I have a line showing up on my device list for a device that is not mounted:





45 AT osp SCRATCH-OST0002-osc-MDT0000 SCRATCH-MDT0000-mdtlov_UUID 1





In fact all bits of that filesystem are unmounted and that will not go away.

If I mount that OST, it doesn't change anything. The entry showing a status of 'AT' is still there



34 UP osd-ldiskfs SCRATCH-MDT0000-osd SCRATCH-MDT0000-osd_UUID 10

35 UP lod SCRATCH-MDT0000-mdtlov SCRATCH-MDT0000-mdtlov_UUID 4

36 UP mdt SCRATCH-MDT0000 SCRATCH-MDT0000_UUID 3

37 UP mdd SCRATCH-MDD0000 SCRATCH-MDD0000_UUID 4

38 UP qmt SCRATCH-QMT0000 SCRATCH-QMT0000_UUID 4

39 UP osp SCRATCH-OST0000-osc-MDT0000 SCRATCH-MDT0000-mdtlov_UUID 5

40 UP osd-ldiskfs SCRATCH-OST0001-osd SCRATCH-OST0001-osd_UUID 5

41 UP obdfilter SCRATCH-OST0001 SCRATCH-OST0001_UUID 5

42 UP osp SCRATCH-OST0001-osc-MDT0000 SCRATCH-MDT0000-mdtlov_UUID 5

43 UP osp SCRATCH-OST0003-osc-MDT0000 SCRATCH-MDT0000-mdtlov_UUID 5

45 AT osp SCRATCH-OST0002-osc-MDT0000 SCRATCH-MDT0000-mdtlov_UUID 1





What is a status of 'AT' and how do I get that OST back online and active? I have tried --writeconf, activate/deactivate fo all OSTs and the MDT. I've run e2fsck on the backing filesystem with no errors.
